The Reality Of Risks From Consented Use Of Usb Devices, Marwan Al-Zarouni

Australian Information Security Management Conference

Physical security is considered an integral part of information systems security. The idea that small devices pose a security threat for enterprises is well established. On the other hand, consented and supervised access to USB ports via USB flash drives is sometimes allowed. This paper will highlight the risk associated with this kind of access by devices such as IPods and USB flash drives. It will show a proof of concept USB device that runs automatically once connected to a personal computer and copies files and folders from the victim's computer to its storage and executes potentially harmful code on …

Qos Issues Of Using Probabilistic Non-Repudiation Protocol In Mobile Ad Hoc Network Environment, Yi-Chi Lin, Jill Slay

Australian Information Security Management Conference

So as to guarantee the fairness of electronic transactions, users may require a NonRepudiation (NR) service in any type of network. However, most existing NR protocols cannot work properly in a Mobile Ad hoc Network (MANET) due to their characteristics (e.g. limited resources and lack of central authority). The design of the Probabilistic NonRepudiation Protocol (PNRP) is comparatively suitable for the nature of a MANET, but it still poses some QoS issues. This article points out the QoS issues which are caused by using PNRP in a MANET environment. These issues explain the difficult of performing PNRP in such an …

Individuals’ Perceptions Of Wireless Security In The Home Environment, Patryk Szewczyk

Australian Information Security Management Conference

Research in 802.11 wireless networking has in the past focused predominantly on corporate wireless network use, or identifying the flaws in wireless security. This study was aimed to determine the individuals’ perceptions of wireless security in the home environment. 163 volunteers completed a survey on their perceptions, knowledge, experiences and attitudes towards wireless networking. The results of the survey indicated that there is little difference in knowledge between those who had worked in the IT industry, and those who did not. The sources of information used to configure wireless networks are not improving the knowledge respondents had on wireless security. …

Secure Transmission Of Shared Electronic Health Records: A Review, Rachel J. Mahncke, Patricia A. Williams

Australian Information Security Management Conference

Paperbased health records together with electronic Patient Management Systems remain the norm for hospitals and primary care practices to manage patient health information in Australia. Although the benefits of recording patient health information into an electronic format known as an electronic health record (EHR) are well documented, the use of these systems has not yet been fully realised. The next advancement for EHRs is the ability to share health records for the primary purpose of improved patient care. This may for example enable a primary care physician, with the patient’s consent, to electronically share pertinent health information with a specialist, …

WiMAX is relatively a new technology; not deployed widely to justify the evidence …

Cyber Crime And Biometric Authentication – The Problem Of Privacy Versus Protection Of Business Assets, Michael G. Crowley

Australian Information Security Management Conference

Cyber crime is now a well recognised international problem that is a major issue for anyone who runs, manages, owns, uses or accesses computer systems linked to the worldwide web. Computer systems are business assets. Personal biometric information is also an asset. Studies have shown that privacy concerns represent a key hurdle to the successful introduction of biometric authentication. In addition, terrorist activity and the resultant legislation have added an additional risk factor businesses need to take into account if they propose using biometric authentication technology. This paper explores the use of biometric authentication to protect business and individual assets. …

Uncontrollable Privacy - The Right That Every Attacker Desires, Giannakis Antoniou, Stefanos Gritzalis

Australian Information Security Management Conference

The request of the Internet users enjoying privacy during their e-activities enforces the Internet society to develop techniques which offer privacy to the Internet users, known as Privacy Enhancing Technologies (PETs). Among the Internet users, there are attackers who desire more than anything else to enjoy privacy during their malicious actions, and a PET is what they were looking for. Thus, although a PET should offer privacy to the internet users, proper techniques should also be employed in order to help the victims during the investigation procedure and unveil the identification of the attackers. The paper summarizes the current design …

Network Forensics And Privacy Enhancing Technologies “Living” Together In Harmony, Giannakis Antoniou, Stefanos Gritzalis

Australian Information Security Management Conference

Privacy Enhancing Technology (PET) is the technology responsible to hide the identification of Internet users, whereas network forensics is a technology responsible to reveal the identification of Internet users who perform illegal actions through the Internet. The paper identifies the collision of these opposite-goal technologies and describes what happens in case they come across. Can a Network Forensics protocol discover the identification of an Internet user who is trying to be anonymous behind a PET? The paper also proposes a way to bridge and eliminate the gap between these two technologies.

A Knowledge Framework For Information Security Modeling, Shuangyan Liu, Ching-Hang Cheung, Lam-For Kwok

Australian Information Security Management Conference

The data collection process for risk assessment highly depends on the security experience of security staffs of an organization. It is difficult to have the right information security staff, who understands both the security requirements and the current security state of an organization and at the same time possesses the skill to perform risk assessment. However, a well defined knowledge model could help to describe categories of knowledge required to guide the data collection process. In this paper, a knowledge framework is introduced, which includes a knowledge model to define the data skeleton of the risk environment of an organization …

Making Research Real: Is Action Research A Suitable Methodology For Medical Information Security Investigations?, Patricia A. Williams

Australian Information Security Management Conference

In the medical field, information security is an important yet vastly underrated issue. Research into the protection of sensitive medical data is often technically focused and does not address information systems and behavioural aspects integral to effective information security implementation. Current information security policy and guidelines are strategically oriented which, whilst relevant to large organisations, are less supportive to smaller enterprises such as primary care practices. Further, the conservative nature of the medical profession has been shown to hinder investigation into information technology use and management, making effective improvement based on research problematical. It is an environment which relies greatly …

The Derivation Of A Conceptual Model For It Security Outsourcing, W D. Wilde, M J. Warren, W Hutchinson

Australian Information Security Management Conference

IT security outsourcing is the establishment of a contractual relationship between an organization with an outside vendor which assumes responsibility for the organisation’s security functions. Outsourcing in IS has had a variable history of success and the complexity of the decision making process leads to a substantial degree of uncertainty. This is especially so in the realm of IS security since the protection of both hardware and software systems is placed in the hands of an external provider. This paper is a fuller and more comprehensive paper of a previous paper outlining the effectiveness of the decision making process by …

Life Data Analysis Of Repairable Systems: A Case Study On Brigham Young University Media Rooms, Stephen Oluaku Manortey

Theses and Dissertations

It is an undisputable fact that most systems, upon consistence usage are bound to fail in the performance of their intended functions at a point in time. When this occurs, various strategies are set in place to restore them back to a satisfactory performance. This may include replacing the failed component with a new one, swapping parts, resetting adjustable parts to mention but a few. Any such system is referred to as a repairable system. There is the need to study these systems and use statistical models to predict their failing time and be able to set modalities in place …

Path Integral Formulation Of Langeinv Dynamics With Applications To Rare-Event Systems, Bradley Dickson

All Dissertations

In the last decade great efforts have been made to efficiently study the behaviors of rare-event systems. The methods and theories developed in pursuit of this goal are far from unified and are instead applied on a case-by-case basis where one makes a best educated guess as to which approach may afford the greatest chance of studying the rare-event system in question. The work contained here is directed at further development of one of these sets of methods and theories. Specifically, a new theory of dynamics in the Langevin path space is developed with emphasis on generating and sampling Langevin …

Visualization Of Polymer Processing At The Continuum Level, Jeremy Hicks

All Theses

Computer animation, coupled with scientific experimentation and modeling, allows scientists to produce detailed visualizations that potentially enable more comprehensive perception of physical phenomena and ultimately, new discoveries. With the use of Maya, an animation and modeling program that incorporates the natural laws of physics to control the behavior of virtual objects in computer animation, data from the modeling of physical processes such as polymer fibers and films can be explored in the visual realm. Currently, few attempts have been made at the continuum level to represent polymer properties via computer animation using advanced graphics. As a result, scientists may be …

Synthesis And Optical Properties Of Four Oligothiophene-Ruthenium Complexes And Synthesis Of A Bidentate Ligand For C-F Bond Activation, Joseph S. Bair

Theses and Dissertations

Photovoltaic cells and fluorescence sensing are two important areas of research in chemistry. The combination of photon-activated electron donors with electron acceptors provides a strong platform for the study of optical devices. A series of four oligothiophene-ruthenium complexes has been synthesized. Variation in oligothiophene length and bipyridine substitution allowed comparison of these variables on electronic properties. The longer oligothiophenes display lower energy absorption and emission compared to the shorter ones. Aromatic conjugation appears more complete with para-, rather than meta-, substitution. Oligothiophenes and Ru(bpy)32+ are highly fluorescent individually, but fluorescence is quenched when connected. Bonds of carbon to fluorine are …

Development Of Polymer Monoliths For The Analysis Of Peptides And Proteins, Binghe Gu

Theses and Dissertations

Several novel polymer monoliths for the analysis of peptides and proteins were synthesized using polyethylene glycol diacrylate (PEGDA) as crosslinker. Photo-initiated copolymerization of polyethylene glycol methyl ether acrylate and PEGDA yielded an inert monolith that could be used for size exclusion liquid chromatography of peptides and proteins. This macroscopically uniform monolith did not shrink or swell in either water or tetrahydrofuran. More importantly, it was found to resist adsorption of both acidic and basic proteins in aqueous buffer without any organic solvent additives. A strong cation-exchange polymer monolith was synthesized by copolymerization of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and PEGDA. A ternary …

Generalized Differentiation Of Parameter-Dependent Sets And Mappings, Boris S. Mordukhovich, Bingwu Wang

Mathematics Research Reports

The paper concerns new aspects of generalized differentiation theory that plays a crucial role in many areas of modern variational analysis, optimization, and their applications. In contrast to the majority of previous developments, we focus here on generalized differentiation of parameter-dependent objects (sets, set-valued mappings, and nonsmooth functions), which naturally appear, e.g., in parametric optimization and related topics. The basic generalized differential constructions needed in this case are different for those known in parameter-independent settings, while they still enjoy comprehensive calculus rules developed in this paper.
